Betty Davis, a funk music trailblazer who was married to jazz great Miles Davis, died Wednesday at 77.

The boundary-smashing artist died of natural causes at 4:40 a.m. at her home in for Homestead, Pennsylvania, according to longtime friend Connie Portis.

“It is with great sadness that I share the news of the passing of Betty Davis, a multitalented music influencer and pioneer rock star, singer, songwriter and fashion icon,” Portis said. “Most of all, Betty was a friend, aunt, niece, and beloved member of her community of Homestead, Pennslvania, and of the worldwide community of friends and fans.”

“At a time to be announced, we will pay tribute to her beautiful, bold and brash persona. Today we cherish her memory as the sweet, thoughtful and reflective person she was. ...There is no other,” she added.
